som module¶
Self Organizing Maps to display high dimensional design spaces.
Classes:
|
Self organizing map clustering optimization history. |
- class gemseo.post.som.SOM(opt_problem)[source]¶
Bases:
gemseo.post.opt_post_processor.OptPostProcessor
Self organizing map clustering optimization history.
Options of the plot method are the x- and y- numbers of cells in the SOM.
- Parameters
opt_problem (OptimizationProblem) – The optimization problem to be post-processed.
- Raises
ValueError – If the JSON grammar file for the options of the post-processor does not exist.
- Return type
None
Attributes:
The default width and height of the figure, in inches.
The Matplotlib figures indexed by a name, or the nameless figure counter.
The paths to the output files.
Methods:
check_options
(**options)Check the options of the post-processor.
execute
([save, show, file_path, ...])Post-process the optimization problem.
- DEFAULT_FIG_SIZE = (12.0, 18.0)¶
The default width and height of the figure, in inches.
- Type
tuple(float, float)
- check_options(**options)¶
Check the options of the post-processor.
- Parameters
**options (Union[int, float, str, bool, Sequence[str]]) – The options of the post-processor.
- Raises
InvalidDataException – If an option is invalid according to the grammar.
- Return type
None
- execute(save=True, show=False, file_path=None, directory_path=None, file_name=None, file_extension=None, fig_size=None, **options)¶
Post-process the optimization problem.
- Parameters
save (bool) –
If True, save the figure.
By default it is set to True.
show (bool) –
If True, display the figure.
By default it is set to False.
file_path (Optional[Union[str, pathlib.Path]]) –
The path of the file to save the figures. If the extension is missing, use
file_extension
. If None, create a file path fromdirectory_path
,file_name
andfile_extension
.By default it is set to None.
directory_path (Optional[Union[str, pathlib.Path]]) –
The path of the directory to save the figures. If None, use the current working directory.
By default it is set to None.
file_name (Optional[str]) –
The name of the file to save the figures. If None, use a default one generated by the post-processing.
By default it is set to None.
file_extension (Optional[str]) –
A file extension, e.g. ‘png’, ‘pdf’, ‘svg’, … If None, use a default file extension.
By default it is set to None.
fig_size (Optional[Tuple[float, float]]) –
The width and height of the figure in inches, e.g. (w, h). If None, use the
DEFAULT_FIG_SIZE
of the post-processor.By default it is set to None.
**options (Union[int, float, str, bool, Sequence[str]]) – The options of the post-processor.
- Returns
The figures, to be customized if not closed.
- Raises
ValueError – If the opt_problem.database is empty.
- Return type
Dict[str, matplotlib.figure.Figure]
- property figures¶
The Matplotlib figures indexed by a name, or the nameless figure counter.
- property output_files¶
The paths to the output files.
